General

The R4600 started shipping in 1994 assthe first microprocessor developed by Quantum Effect Devices, Inc. and implements the MIPS III instruction set in a simple but effective 5-stage pipeline. It's very similar to the R4000 and R4400 processors but unlike these there is no integrated second level cache controller.

R4700

The R4700 represents kind of an R4600 second edition. It's virtually identical but offers slightly faster floating point performance. The only workstation vender to use the R4700 was Siemens-Nixdorf in a variant of the RM 200 C workstation. Linux supports the R4700 but this hasn't actually been tested since several years.
